parseInt

The parseInt task parses a string value and returns an integer (number) value using the decimal number system as a mathematical base. Only the first number in the string is returned. If the string argument is not a string, it is converted to a string using the ToString abstract operation. Leading whitespace in the string is ignored.

Potential use case

This task is useful when you need to convert a number represented as a string into an integer. For example, if your data string contains a decimal value such as "1.655", parseInt will convert the decimal value to the rounded number 1, and the digits that follow the decimal will be truncated.

Properties

Example 1

In this example:

• The incoming string variable str is statically set to 0xF, which is a hexadecimal representation.
• The radix number is set to 16, which is a hexadecimal number.

The result of the outgoing variable is 15.

Example 2

In this example:

• The incoming string variable str is statically set to 02019 4 29. Notice the white spaces within the reference variable.
• No radix number is provided, so the default decimal value (10) is used.

The result of the outgoing variable is 2019.

Example 3

In this example:

• The incoming string variable str is statically set to 5.99.
• No radix number is provided, so the default decimal value (10) is used.

The result of the outgoing variable is 5. The numbers after the decimal are truncated.

Example 4

In this example:

• The incoming string variable str is statically set to 7,123. Notice the value contains a comma.
• No radix number is provided, so the default decimal value (10) is used.

The result of the outgoing variable is 7. The numbers after the comma are truncated.

Example 5

In this example:

• The incoming string variable str is set to 20*4. Notice the operator (asterisk) within the reference variable.
• No radix number is provided, so the default decimal value (10) is used.

The result of the outgoing variable is 20.
